The Chinese attitude to suicide is completely different to the one in the west, which everyone commenting here is missing. Worker suicides would cause a tremendous loss of face for Foxconn while preserving the face of the workers' families. The point of an anti-suicide contract is not to prevent people from feeling suicidal but to prevent the individual who signs it from holding that over Foxconn as a threat. If someone committed suicide after signing such a contract, the contract has priority and the loss of face would be from the worker's family.
